borla hush on my 04 wagon for a few months now. like others have said, it doesn't exactly live up to the name "hush" but it's still _fairly_ quiet. you can hear it on the highway but i'd say if you can deal with loud sticky tires, it's definately something you could deal with. i wouldn't worry about it. i'm not having any problems and i really don't like loud exhausts.

are you cat-less?
after i get my Helix DP, we could compare them (Hush vs. Evo2) since you are in town.
